SPECIFICATION forming part of Letters Patent No'. 508,696, dated November 14, 1893. Application filed December 28,1892. Serial No. 456,521.` (No model To a/ZZ whom t may concern,.-

Be it known that'I, ACHILLE GIACOMINI, of the city. of St. Louis and- State of Missouri,

have invented certain new andvkuseful lm provements in Machines for Grain'ing Wood,

of which the following is a full, clear, andy ex-y act description, reference being hadto the accompanying drawings, forming a part hereof.

My invention relates to improvements in a machine for graining wood and consists in the novel arrangement and combination ofV treated in a certain manner imitates woodsl of higher and Inore expensive grades.

In the drawings: Figure 1, is a side elevation of my complete invention.` Fig. 2 is a detailed view of the indenting roller showing its particular construction. Fig. 3 is an end view of one of the removable indenting plages,

1g. 4 is a detail end view otl a separating-plate used as hereinafter described. Fig. 5 is a detail sectional viewwith parts broken away, of a number ofA plates provided with indeuting projections, which are so placed as to imprint the figure ofa Womans head* Fig. 6 1s a detail view of a number of thevremovable plates which are providedy withiraised letters 'or Referring to the drawings :-1, indicates the two side standards which support the workingl parts of my invention Ih /Iounted substantially intermediate of the height-of said standards is a feed-roller 2 indicated in the drawings by dotted lines, and mounted upon a shaft-.3 upon the projecting end of which is secured a pulley 4, by vmeans of which the roller is operated. Projecting outwardly from bothi sides of the standards 1 are curvilinear upwardly extending arms 5, each ofwhich is provided with curvilinear slots 6, the slot in each of said arms 5 at each end of the machine being in alignment to receive the pro#H jecting ends of shafts 7 upon which are mounted contact rollers 8 which-areadjustfl; able vertically'in'sa'id slots 6 'by means of;V .th,e v. nuts 9 upon the ends vof said shaft 7. Two

upwardly proj ecting guides 10 provide guides l foi` the vertical reciprocatory movement of bearing blocks 11, in which the endsof the shaft 12 have their bearings. The bearing blocks 11 are provided with upwardly projecting screw-threaded rods 13 which are adapted to operate in an interiorly screw threaded opening (not shown) in the cap 14 surmounting the two upright guides 10. The bearing blocks upon both sides of the machine are similar and provided with gear-wheels 15, keyed thereon and adapted to be engaged by small worms 16 mounted upon a horizontal shaft, and the revolving of-:which revolves said wheels 15 and raises the bearing blocks 11 and consequently the roller 17 upon the shaft 12, said Ioller 17 being formed bya number of removable adjustable plates 18 and 19. A number of plates such as 18 or 19 or both are provided with five openings, a central one 2O to fit over a shaft 12, and four smaller radially arranged openings 22v to fit upon rods 23. Adjustable heads 24 are adapted to be vsecured in a desired position upon the shaft 12 by set -screws 25.v The rods 23 extend through the two heads 24 and through any number of plates 18 or 19 that it is desired to make use of. The plates are placed between said'heads 24 and upon said rods 23 and shafts 12 and held in place by the adj ustment of nuts 26 upon said rods 23. The plates 18 may beof any desired thickness and if it is desired by their use to imitate the grain of any certain wood, irregular projections 27 are provided upon theirv peripheries, which when in position upon the roller appear something like theA design shown in Fig. 2 imitating the grain ofswood. As is also shown in the same figure, the plates are'made ofdifferent widths or diameters and with slanting or rounded edges, in order to form projecting designs upon moldings and other irregular surfaces of Wood work. The indentations upon the yroller impinge the surface of'thewoodwhich is run over the rollers 8 and between the rollers 17 and 2. The indentatious made in the surface of the 'wood are filled with any desired, color of material and then the material to be grained is treated withvarnish and iinishing compounds in a ,ilm'anner well known 'to the trade. The plates 19 are of the same diameter as the plates 18 without the projecting portions 27 and are ICO ` isknown as a hand process.` f

adapted to be placed between the plates 18 when it is not desired to leave any graining mark upon' certain portions'of*thelvfodrf'The plates may be `formed with such "projections upon their peripheries as will leave the irnprint ofa human head as shown iu Fig. 5 or with letters as shown in Fig. 6, or in factany design which it may be desired 'to reprod licei' upon Wood or other material.

The especial feature of my invention lies in the fact that any number of the plates may be used to form a roller and any design of graining or other figure can be made by the adjustment of one set of plates as Wellas the" adaptability of same to'be used infgraining, 'f

moulding or other forms of wood which here1- toforehave necessarily been grained by what Theplates 18 andl9`ar`e adj ustably mounted uponthe shaft 12 and the rods 23, so that theyl may be moved horizont-ally thereon and adjusted to .different-ielative positions a'Xiallyto\produce.designs of dierent configurations :with a single set of plates, as shown. Theplates 18 of less diameter, are, as,v be-f forestated, set in suchrelative position as to form peripheral or annular depressions inf the, graining roll, which are `adapted to 'lit over their-regular surface of moldings or other, woodwork and impart to such surfaces `indentationssimulating the grainof natural woodr andwspecial designs- I` desire to' pointyout thatall of said plates are axially adj ustable' upon the shaft 12, sothat their relative posi-M tions may be changed l at will; AllA that-is necessaryin making the change-to producen: dierent design is to loosen the nuts 26 upon the rods 23, remove the heads y-or faceplates 17,s or ,one of them, then remove as nranyof theplates 18 and 19 as desired, and *replacer same f in a diercnt relativeposition fromthatfwhich they formerly occupied. When- I describe said plates as having d ierent diameters'y I mean that there Aisa series of-y plates18 having diiferent diameters, and also a seriesofplates 19 having dierent diame tersfasd do not consider theV projections 247-A uponthe plates 18 as addingto their diame':y ters. .Itwill be observed that when I locate a series of Yplates 18finfsuch. relative posii` tions adjacent each-othexg-a numberof such plates have diierent diameters and are located closelyadjacent each other, withplatesj 19 ofudierent diameters located alternately betweenA adjacent `plates 18, -for the 'above specified purpose. It will be observedthat the shaft 12 and the rods 23 areof such length that a graininga'oll of sufficient lengthfto en-f gagefthe inner surface of a .comparativelyF wide-board or plank, is provided. It will bel further observed that the plates upon 4said shaftand said rods are removable or interchangeable at either end of said shaft and rods Both ends of said shaft and rods are provided with adjusting devices, iso thatjby means of the nuts 26 and thethreaded oppothereon may be clamped together and urged toward the center of the length of said shaft aiidsaid rods', `by"adjustii1g"the'said' nuts at eimer "nd'f sardrods; This provides a construction which is Very accessible and convenient in operation, for obvious reasons. The series of rods 23 parallel with the shaft Ziandfengagingiftld "radially located holes or apertures 22 in all of the disks at separate radial points therein, act very effectually to preventfrelative'aial movement of said disks upon said shaft, and to hold said disks with l their projections 27 in the fixed relative position to 'Whichltlieylhave been adjusted by the operator;"flwdesirealsd to point out that by the use of the series of clamping rods 23 with nuts threaded upon` theirends, the series of disks 0r Plates. 18. edili? are Very. .Securely damped iosethel'iet dilferentinoints in.. .their Surfdestherbi' prereeting.bendingobuek: lihg ilfeny'slisk et any. point:
